Pink Salmon Swimming Upstream : Autumn on the Shiretoko Peninsula

カラフトマス 知床半島 秋 遡上 Pink Salmon run Shiretoko Peninsula (3)

Pink Salmon, called “Kurafuto masu” in Japanese, return to the rivers on the Shiretoko Peninsula. These salmon came from the rivers and migrated out into the Northern seas for about two years; then return to their natal rivers to spawn.

These salmon just in front of me are on the verge of death. The Pink Salmon embody the very raw ‘act of living’ in their tattered appearance. We, who eat these salmon, must have gratitude in our hearts.

Salmon Run- Pink Salmon Going Upstream in the Fall in Shiretoko Peninsula

Compared to other salmon species, the Pink Salmon do not have a strong “Homing Instinct” and will swim upstream of any freshwater rivers nearby. In the year this video was filmed (2016), the peninsula had experienced 3 typhoons in mid-August. This had caused the salmon net that had been set along the coast to come loose, and it enabled a large number of salmon to make it upstream.
